Packing failures

Leak Leaks are typically developed from valve or pump seal packing failures, localized corrosion or erosion effects and are typically "small" to "pin-hole" sized (e.g., corrosion or erosion leakages).

If a lab must be moved or for any reason needs to be set up again, this can be achieved. It takes 8 hours for a lab to be properly packed. Failure to properly pack a lab before moving results in a loss of lab chemicals and equipment. This subtracts from the DC bonus normally granted for a complete and functioning lab. This loss is determined at the GM s discretion. 

Undesirable adhesion to metal surfaces may cause a problem in injection molding, melt spinning, and thermoforming. In the melt spinning of PAS a variety of adhesion-related problems have been observed. These problems include the build up of polymer on spinneret surfaces resulting from both initial filament extrusion and lick-back from filament breaks. These adhesion-related problems lead to prematme spin pack failure and equipment down-time to replace spent spinneret packs, and can limit the use of PAS in certain melt spinning operations.

Sprays or Mists—Medium sized releases of moderate frequencies that are mixed immediately into the air upon release. Typically pipe gasket, pump seal, and valve stem packing failures under high pressure. On occasion release from flare stacks. 

Eurther heat treatment in excess of 2000°C is referred to as graphitization. Eiber stmcture further densifies as molecular packing and orientation increase. At temperatures of 3000°C or above, the fiber stmcture begins to approach a truly graphitic stmcture with three-dimensional order. Typically, fiber strain to failure decreases as the carbonization temperature exceeds 1500°C because of reaction of impurities with the carbon fiber and the development of an increasingly flaw-sensitive graphitic stmcture (31,34)...

On initial start-up and shut-down the heat exchanger can be subjected to damaging thermal shock, overpressure or hydraulic hammer. This can lead to leaky tube-to-tubesheet joints, damaged expansion joints or packing glands because of excessive axial thermal, expansion of the tubes or shell. Excessive shell side flowrates during the "shake down can cause tube vibrations and catastrophic failure.
